The Silver King.

The following condenced extracts are from the annual official report of Super intedent Macy made to the King stock holders on the r ut:
 The operations at the mine have been carried on without interruption during the year, excepting stoppage for "A hours on Christina 5s day Co overhaul the hOisting engine and compressor, and 2s,076 tons of ore have been extracted from the levels under exploitation and sent tO the mill. The surisce quarry has been worked as heretofore, by bressting into the side of the hill in which lies the old "Open pit'-cOnnec- ton haying been made with ssme--tO furnish waste rock for filling in the absn- dOned stOpes of the mine, and 10 obtain such ore as was opened tO us in the pro gress of the work. From this source AZ tons of ore were produced and seat to Mill No, for treatment, thus making the entire output of ore for the year. 2S. 5I3 tons. or about l,000 tons more than the previous year. The distribu- tiun to the two mills was 22, 2,066 tons Co Mill No. and AT 10 Mill No. ?.
 The work uf the year m the mine has been confined to she 20, 3j0, 4OJ, 6OO and Sg0 levels, the principal portion hay ing been done on the GtO level.
 The total amount of ore treated at Mill No, was 22,947.07 tons, the year opening with considerable reserve on .Le mill yard. The average assay vs,us of the ore was 270S ounces silver per ton. The product was 56 shipments of con centratiOns. averaging 1 ]. S27, loo tons each and Bgsregating 634 294. loo tons. The ore shipped was 66 per cent of that crush ed. and of the si,ver contents of the con- centrRtiOn, 34 A per cent was in the form of native silver, J6-56 per cent, being confined in the various srgentIiOrous sulphides. The actual average working loss, per ton of ore treated, was 3.64 ounces silver per ton, or 1340 per cent. of the average value of ore crushed the value In tailings resting chIetiy in argeni iiferous zinc blendes.
 There have also been treated dnring the year 7S9la tons Of second class con centrHtlon and old t8llings. the cOncen- .rates being made up of the product ot both 'eluice" and vBuEer work. Some of the work was experimental, but towards the close of the year the hand ling of material from the second set of vsnners was in the lIne of regular treat ment. The product from the treatment nf this material was l6, 446 Ounces Of hne silver, and although of very Tefac- tory constituency the concentrates were worked to 67 s3 percent of their origins al assay value. Some changes are con- templHted at Rn early day to work this material tO higher percentage. when It Is expected that not less than 75,OOO ounces of fine silver can be recovered per anuum from this treatment of Origi- nAl ts;lIOgs by concentration and anal yamatiOn. The entire output for the year from Mill No. , consisted of 202 bars of bullion ut Ra average fineness of 723 10 loo thousandths, the bars aver aging 22O3S3 troy vuuoss m weight. The consumption Of quicksilver in the treatment Ot secOnd-ciass material was l. - pounds per ton.
 The consumption of fuel at the mills was 5.S0O cords of wood ranging in cost from S7.45 to S9. 5O per cord, of which 4, l4I cords were consumed under tke boilers, together with li9l5 tons of coal eIperimenially burned.
 We close the year with an abundant supply ot cord wood and general sup plies at both mills, and ore reserves in the respective mill yards of 4i6 tons for Mill No. l, and 4lG tons for Mill No. 2
 The outlook for the new year IS very tiB,terlng, with large ore reserves de yelopei and in sigh, ID the mine,
